Optimizing battery life
You can extend your battery’s life between charges by turning off features that you don’t need. You can also monitor how applications and
system resources consume battery power.
To guarantee the optimal performance of your battery, please stick to the following rules:
 Turn off radios that you aren’t using. If you aren’t using Wi-Fi, Bluetooth, or GPRS, use the Setting application to turn them off.
